TOBACCO-PIPE.

Specification of Letters Patent.

Patented Sept. 11, l1906.

Application tiled January 16.1906. Serial No. 296,378.

To all whom, it may concern.'

Be it known that I, LoRENs SwENsoN, a citizen of the United States,residing at Cresco, in the county of Howard and State of Iowa, haveinvented new and useful Im-I provements in Tobacco-Pipes, of which thefollowing is a speciiication.

My invention pertains to tobacco-pipes,- and it has for its object toprovide a tobaccopipe embodying' a simple and inexpensive constructionand arrangement of chambers for robbing the smoke of nicotin andassuring the smoke being cooled to a considerable extent before itreaches the mouth of the smoker and one susceptible of beingexpeditiously and thoroughly cleared of collected nicotin and othersediment when the same is necessary.

Vith the foregoing in mind the invention will be fully understood fromthe following description and claim when the same are considered inconnection with the accompanying drawings, forming part of thisspecification. in which Figure 1 is a longitudinal vertical section ofmy novel tobacco-pipe. Fig. 2 is a side elevation of the mouthpiece ofthe pipe removed, and Fig. 3 is a longitudinal vertical section of amodified stem hereinafter referred to in detail.

Referring by letter to the said drawings, and more particularly'to Figs.l and 2 thereof, A is the bowl, and B the stem, of the pipe constitutingthe preferred embodiment of myinvention. The bowl A is provided at apoint adjacent to its bottom with a smoke-passage c and is otherwise ofthe ordinary welliown construction. It may obviously be made of anymaterial compatible with my invention and in various shapes and sizes atthe The stem B is formed integral with the bowl A and comprises a lowerchamber b, whichA exten ds throughout its length and is connected at itsforward end to the passage a of the bowl and is open at its rear end, anupper chamber c, open at its rear end and interiorly threaded at suchend, as indicated by d, and a port or passage e, formed in the wall fbetween the chambers?) and c, so as to connect the rear portions of thechambers, for a purpose presently set forth. C is the removablemouthpiece of the pipe. The said mouthpiece has an exteriorly-tlneadedportion g, designed to engage the thread d in chamber c, and shoulders hand i, designed to bear against the rear ends of the chambers c and t,respectively, and it also has a forwardly-extending portion c, theforward end of which rests adjacent to the forward end of the chamber c,as illustrated, for a made clear. bringing up against the rear ends ofthe chambers c and b to limit the inward movement of the mouthpiece andadd to the inish of the pipe, and the shoulder i. also serves toeffectually close the rear end of the chamber t. It will be noticed,however, that when the mouthpiece C .is detached and withdrawn from thestem B the rear ends of the chambers b and c are left entirelyuncovered, and hence said chambers may be expeditiously and thoroughlycleared of collected nicotin and other sediment with but a minimumamount of effort. It will also be noticed that when removed from thestem B the interior and exterior portion 7c of the mouthpiece C may bequickly and easily cleaned.

l/Vhen the mouthpiece C is positioned in and attached to the stem B, asshown in Fig. l, and the pipe is used, it will be apparent that en routefrom the bowl A to the outlet of the mouthpiece C the smoke must passthrough the passage a, the chamber b, the port e, and the bore of themouthpiece in the order named. It will also be apparent that because ofthe longitudinal chambers b and c being parallel and the port e and theforward end of the mouthpiece portion 7c being relatively arranged, asshown in Fig. 1, the smoke in taking the course described must traversethe full length of the channel b, the full length of the chamber c, andthe full length of the mouthpiece C. From this it follows that by thetime the smoke reaches the mouth of the smoker nicotin will bepractically eliminated from the smoke, and the smoke will be cooled tosuch an extent as to avoid annoyance to the smoker.

Vhen it is necessary to clean my novel pipe, the mouthpiece C isdetached and withdrawn from the stem B, so that access may be readilygained to the interior of all of I the parts, as before described.

I In Fig. 3 ofthe drawings I have illustrated l a stem B', which issimilar in construction to the stem B of Fig. 1 with the exception thatit is provided with a forward reduced portion B2. The said reducedportion BZ is designed to be arranged and frictionally held in thesuitable bowl and to bore of a clay or other i be removed therefrom whendesired. The

6o y purpose which will presentlybe .I The shoulders 7i and 'i serve byIOO IIO

i this it follows that When the mouthpiece C is expeditiously andthoroughly cleared of colmade of one piece and having thereinlongitumodiied stem B is designed to be used in l connection with themouthpiece C and isV ob# viously possessed of all of the practicaladvantages hereinbeiore ascribed to the stem B oi Fig. 1.

removed both chambers of the stem may be lected sediment.

I claim- ,my hand in presence of The combination of a tobacco-pipe stem1' dinal chambers arranged one above the other and separated by alongitudinal Wall and 'I open at their rear ends and connected adjacentto said ends by an intermediate passage Jformed in the said longitudinalWall; one of said chambers being closed at its Jforward end and havingan interior thread in its rear portion and the other being provided atits for- Ward `end with an inlet for smoke, and a mouthpiece having aneXteriorly-threaded portion removably arranged in the rear threaded endof the first-mentioned chamber and a forwardly-extending portiondisposed in said chamber and also having a shoulder disposed entirely inrear of and closing the rear end of the other chamber.
